[Some of those problems, %%% though not that of the Kepler Conjecture, are %%% included in the Clay Mathematics Institute %%% Millennium Problem list for which validated %%% solutions win a prize of one million US %%% dollars.] %%% %%% Thomas C. Hales announced a proof of the %%% Kepler Conjecture on 9 August 1998, so it %%% should now be called the Kepler Theorem, but %%% the proof was not published until 2005. See %%% entry Morgan:2005:BRB for the reasons for the %%% long delay in publication, and entry %%% Hales:2000:CH for the prize-winning paper %%% with a largely nonmathematical description of %%% the nature of the problem. %%% %%% Hales' complicated proof is detailed in a %%% book (entry Lagarias:2011:KCH), and discussed %%% in nonmathematical form in two other books %%% (entries Casti:2001:MMF and Szpiro:2003:KCH). %%% The proof was also published in seven papers %%% in a special journal issue (entries %%% Hales:2006:SPIb, Toth:2006:GEF, %%% Ferguson:2006:SPV, Hales:2006:SPV, %%% Hales:2006:FKC, Hales:2006:HOK, %%% Hales:2006:SPIa). %%% %%% Because of the great difficulty of the proof %%% of the Kepler Conjecture, and the inability %%% of other mathematicians to verify the proof, %%% Hales began Project Flyspeck (see entry %%% Hales:2008:FP) to produce a verification of %%% the proof by a computer. Successful %%% completion of that project was announced on %%% various e-mail lists on 10-Aug-2014. Hales %%% reported: %%% %%% ``The verification of all nonlinear %%% inequalities in HOL Light on the %%% Microsoft Azure cloud took approximately %%% 5000 processor-hours. Almost all %%% verifications were made in parallel with %%% 32 cores, hence the real time is about %%% 5000 / 32 = 156.25 hours. Nonlinear %%% inequalities were verified with compiled %%% versions of HOL Light and the %%% verification tool developed in Solovyev's %%% 2012 thesis.'' %%% %%% The final report of that project appears in %%% entry Hales:2015:FPK. Entry Adams:2014:FF %%% discusses the proof, and the independent %%% validation of the proof. %%% %%% In June 2020, the London Mathematical Society %%% awarded the Senior Berwick Prize to Thomas %%% Hales for his 2012 book, Dense Sphere %%% Packings: a Blueprint for Formal Proofs %%% (entry Hales:2012:DSP). %%% %%% The checksum field above contains a CRC-16 %%% checksum as the first value, followed by the %%% equivalent of the standard UNIX wc (word %%% count) utility output of lines, words, and %%% characters.

With wires all the same radius, packing fractions as high as $ 0.90690$ can be achieved. However, when the wires are pairs that have been twisted to avoid crosstalk, the packing fraction is much smaller. The largest obtainable packing fraction depends on other properties of the packing. For example, with pairs twisted by machine, all pairs twist at the same rate, and that influences the packing fraction. Several packing problems are considered, but most attention is given to a particularly regular kind of packing in which pairs twist about straight parallel axes located in a lattice arrangement. The densest lattice packing has packing fraction $ 0.56767$. The densest lattice is a complicated one in which each wire touches $ 10$ wires belonging to $6$ other pairs. The numbers $ 10$ and $6$ cannot be increased even with nonlattice packings of pairs with straight parallel axes.

Here we discuss the solution that Hales found in 1998. Almost every part of the 282-page proof relies on long computer verifications. Random matrix theory was developed by physicists to describe the spectra of complex nuclei. In particular, the statistical fluctuations of the eigenvalues (``the energy levels'') follow certain universal laws based on symmetry types. We describe these and then discuss the remarkable appearance of these laws for zeros of the Riemann zeta function (which is the generating function for prime numbers and is the last special function from the last century that is not understood today.)

We have known since Church and Turing independently showed that mathematical provability was undecidable that there are theorems whose shortest proofs are enormous. Within the last half-century we have discovered practical examples of such theorems: the classification of all finite simple groups, the Four Colour Theorem and Kepler's Conjecture. These theorems were only proved with the aid of a computer. But computer proof is very controversial, with many mathematicians refusing to accept a proof that has not been thoroughly checked and understood by a human. The choice seems to be between either abandoning the investigation of theorems whose only proofs are enormous or changing traditional mathematical practice to include computer-aided proofs.

We explain why an isocounting conjecture, which states that for large disordered jammed packings the average contact number per particle is twice the number of degrees of freedom per particle ($ \bar {Z} = 2 d_f$), does not apply to nonspherical particles. We develop first- and second-order conditions for jamming and demonstrate that packings of nonspherical particles can be jammed even though they are underconstrained (hypoconstrained, $ \bar {Z} < 2 d_f$). We apply an algorithm using these conditions to computer-generated hypoconstrained ellipsoid and ellipse packings and demonstrate that our algorithm does produce jammed packings, even close to the sphere point.

Most studies of the densest packings in three dimensions have considered spherical shapes, and it is only more recently that nonspherical shapes (e.g., ellipsoids) have been investigated. Superballs (whose shapes are defined by $ |x1 |^{2p} + |x2 |^{2p} + |x3 |^{2p} <= 1$) provide a versatile family of convex particles ($ p \geq 0.5$) with both cubic-like and octahedral-like shapes as well as concave particles ($ 0 < p < 0.5$) with octahedral-like shapes. In this paper, we provide analytical constructions for the densest known superball packings for all convex and concave cases. The candidate maximally dense packings are certain families of Bravais lattice packings (in which each particle has 12 contacting neighbors) possessing the global symmetries that are consistent with certain symmetries of a superball. We also provide strong evidence that our packings for convex superballs ($ p >= 0.5$) are most likely the optimal ones. The maximal packing density as a function of $p$ is nonanalytic at the sphere point ($ p = 1$) and increases dramatically as p moves away from unity. Two more nontrivial nonanalytic behaviors occur at $ p_c^* >= 1.150 9...$ and $ p_o^* = \ln 3 / \ln 4 = 0.792 4...$ for cubic and octahedral superballs, respectively, where different Bravais lattice packings possess the same densities. The packing characteristics determined by the broken rotational symmetry of superballs are similar to but richer than their two-dimensional superdisk counterparts [Y. Jiao et al., Phys. Rev. Lett. 100, 245504 (2008)] and are distinctly different from that of ellipsoid packings. Our candidate optimal superball packings provide a starting point to quantify the equilibrium phase behavior of superball systems, which should deepen our understanding of the statistical thermodynamics of nonspherical-particle systems.", acknowledgement = ack-nhfb, fjournal = "Physical Review E (Statistical physics, plasmas, fluids, and related interdisciplinary topics)", journal-URL = "http://pre.aps.org/browse", pagecount = "12", } @Article{Kallus:2009:DPP, author = "Y.

The preponderance of previous work has focused on spherical particles and very little is known about dense polyhedral packings. We formulate the problem of generating dense packings of nonoverlapping, nontiling polyhedra within an adaptive fundamental cell subject to periodic boundary conditions as an optimization problem, which we call the adaptive shrinking cell (ASC) scheme. This optimization problem is solved here (using a variety of multiparticle initial configurations) to find the dense packings of each of the Platonic solids in three-dimensional Euclidean space $ \mathbb {R}^3 $, except for the cube, which is the only Platonic solid that tiles space. We find the densest known packings of tetrahedra, icosahedra, dodecahedra, and octahedra with densities 0.823\ldots, 0.836\ldots, 0.904\ldots, and 0.947\ldots, respectively. It is noteworthy that the densest tetrahedral packing possesses no long-range order. Unlike the densest tetrahedral packing, which must not be a Bravais lattice packing, the densest packings of the other nontiling Platonic solids that we obtain are their previously known optimal (Bravais) lattice packings. We also derive a simple upper bound on the maximal density of packings of congruent nonspherical particles and apply it to Platonic solids, Archimedean solids, superballs, and ellipsoids. Provided that what we term the ``asphericity'' (ratio of the circumradius to inradius) is sufficiently small, the upper bounds are relatively tight and thus close to the corresponding densities of the optimal lattice packings of the centrally symmetric Platonic and Archimedean solids. Our simulation results, rigorous upper bounds, and other theoretical arguments lead us to the conjecture that the densest packings of Platonic and Archimedean solids with central symmetry are given by their corresponding densest lattice packings. This can be regarded to be the analog of Kepler's sphere conjecture for these solids. The truncated tetrahedron is the only non-centrally symmetric Archimedean solid, the densest known packing of which is a non-lattice packing with density at least as high as $ 23 / 24 = 0.958 ~333 ~ \ldots {} $. We discuss the validity of our conjecture to packings of superballs, prisms, and antiprisms as well as to high-dimensional analogs of the Platonic solids. In addition, we conjecture that the optimal packing of any convex, congruent polyhedron without central symmetry generally is not a lattice packing. Finally, we discuss the possible applications and generalizations of the ASC scheme in predicting the crystal structures of polyhedral nanoparticles and the study of random packings of hard polyhedra.", acknowledgement = ack-nhfb, fjournal = "Physical Review E (Statistical physics, plasmas, fluids, and related interdisciplinary topics)", journal-URL = "http://pre.aps.org/browse", keywords = "Kepler sphere-packing conjecture", PACS = "05.20.Jj; 45.70.An; 61.50.Ah", } @Article{vanMeel:2009:GFS, author = "J.

Our approach uses multi-commodity flows to deform the geometry of the graph; we embed the resulting metric into Euclidean space to recover a bound on the Rayleigh quotient. Using this, we show that every $n$-vertex graph of genus $g$ and maximum degree $D$ satisfies $ \lambda_2 (G) = O((g + 1)^3 D / n)$. This recovers the $ O(D / n)$ bound of Spielman and Teng for planar graphs, and compares to Kelner's bound of $ O((g + 1)p o l y(D) / n)$, but our proof does not make use of conformal mappings or circle packings. We are thus able to extend this to resolve positively a conjecture of Spielman and Teng, by proving that $ \lambda_2 (G) = O(D h^6 \log h / n)$ whenever $G$ is $ K_h$-minor free. This shows, in particular, that spectral partitioning can be used to recover $ O(\sqrt n)$-sized separators in bounded degree graphs that exclude a fixed minor. We extend this further by obtaining nearly optimal bounds on $ \lambda_2$ for graphs that exclude small-depth minors in the sense of Plotkin, Rao, and Smith. Consequently, we show that spectral algorithms find separators of sublinear size in a general class of geometric graphs.\par Moreover, while the standard ``sweep'' algorithm applied to the second eigenvector may fail to find good quotient cuts in graphs of unbounded degree, our approach produces a vector that works for {\em arbitrary\/} graphs. This yields an alternate proof of the well-known nonplanar separator theorem of Alon, Seymour, and Thomas that states that every excluded-minor family of graphs has $ O(\sqrt n)$-node balanced separators.", acknowledgement = ack-nhfb, articleno = "13", fjournal = "Journal of the Association for Computing Machinery", journal-URL = "http://portal.acm.org/browse_dl.cfm?idx=J401", keywords = "Metric embeddings; network flows; spectral graph theory", } @Article{Chen:2010:DCD, author = "Elizabeth R.

In this paper we apply the Torquato--Jiao packing algorithm, which is a method based on solving a sequence of linear programs, to robustly reproduce the densest known lattice sphere packings for dimensions 2 through 19. We show that the TJ algorithm is appreciably more efficient at solving these problems than previously published methods. Indeed, in some dimensions, the former procedure can be as much as three orders of magnitude faster at finding the optimal solutions than earlier ones.

Here, we demonstrate that the packing density ($ \theta_f$) of compacted rigid aggregates is independent of spatial scale for systems under weak compaction. The $ \theta_f$ of rigid aggregated structures across six orders of magnitude were measured using nanoscale spherical soot aerosol composed of aggregates with 17-nm monomeric subunits and aggregates made from uniform monomeric 6-mm spherical subunits at the macroscale. We find $ \theta_f = 0.36 \pm 0.02$ at both dimensions. These values are remarkably similar to $ \theta_f$ observed for comet nuclei and measured values of other rigid aggregated systems across a wide variety of spatial and formative conditions.

Generally speaking, analytical solution approaches cannot be expected to apply to this general problem-type, except for very small or certain specially structured sphere configurations. In order to find high-quality numerical (approximate) solutions, we propose a suitable combination of heuristic strategies with constrained global and local nonlinear optimization. We present numerical results for non-trivial model instance-classes of optimized sphere configurations with up to $ n = 50$ spheres in dimensions $ d = 2, 3, 4$. Our numerical results for an intensively studied model-class in $ R^2$ are on average within 1\% of the entire set of best known results, with new optimized (conjectured) packings for previously unexplored generalizations of the same model-class in $ R^d$ with $ d = 3, 4$.

Because the metatiles admit tilings of the plane, so too does the hat.
